CSAT3B Three-Dimensional Sonic Anemometer
To collect data through another means (CPI, RS-485, USB), the
CSAT3BCBL1 Power/SDM cable may still be used to provide
power to the CSAT3B, in which case the SDM wires should be
left unwired to any ports on the datalogger.

Power Cable (CSAT3BCBL2)
To use CPI, RS-485, or USB communications to collect data from a CSAT3B,
the CSAT3BCBL2-L-PT or CSAT3BCBL2-L-MC should be ordered to
provide power to the sensor. A second cable to transmit the communications is
also required (for example, CSAT3BCBL3 CPI/RS-485 cable for CPI or
RS-485, or the 30179 USB data cable).
For installations with long cable lengths, the CSAT3BCBL2 is preferred over
the CSAT3BCBL1 for providing power due to the heavier gauge wires that
reduce voltage drop over long distances.

CPI/RS-485 Cable (CSAT3BCBL3)
To use CPI or RS-485 communications to collect data from a CSAT3B, the
CSAT3BCBL3-L-PT, CSAT3BCBL3-L-RJ, or CSAT3BCBL3-L-MC, should
be ordered in addition to a cable to provide power to the sensor (for example,
either the CSAT3BCBL1 or CSAT3CBL2).
